General CTD Notes
RINKO oxygen sensor run as secondary O2 mounted vertically for casts 001-067, then mounted horizonatally. CTD files only contain Seabird 43 oxygen data as primary O2. RINKO data are available and may be imported into the CTD csvs (programming required- stayed tuned).
CalCOFI 1210NH had problems with bottle tripping and closure confirmations. Solutions attempted after using the deck unit only to trip bottles: switching to the backup CTD computer, from primary Windows XP CTD PC to backup Windows 7 CTD PC - still no comfirmations; new CTD to Carousel cable installed after cast 6 appeared to solve the problem. But the problem reappeared so what finally solved the issue was rewiring the termination - 4-individual-wire termination resulted in the solution. Only used the black & white wires only; red & green were not used. One wire for signal and shield for ground.

Casts affected - 004 93.3 28.0; 005 93.3 30.0; 006 93.3 35.0

2017 note on RINKO data: it was discovered during the 2017 reprocessing, that casts 005, 007, & 026 had pressure-to-depth calculation errors in the downcast RINKO data provided by ODF. These data have been corrected in the 'finalQC' CTD.csvs.
Cast 005: the miscalculation occurs at 260m; Cast 007: miscalculations at 42-43m; Cast 026: miscalculations at 246-247m.

08Mar2017 other than the RINKO error mentioned above, the reprocessing adds data-quality code columns and data codes on bad or missing data ("9"), or questionable data ("8"). Data values should not have changed from the previously published final CTD data. But the column number on updated CTD.csvs has changed from 65 to 82.
Refer to the CTD.csv data format webpage: 65-column index; 82-column index

2017 Updates - Re-merged the CTD asc files with sta.csvs to generate new CTD.csvs with data quality code columns.
The original cruise-corrected coefficients from comparison to final data were not changed so CTD data from the
older zip archive (20-1210NH_CTDFinal.zip May 2015) and this updated archive should be the same.
Station-corrected are calculated dynamically and with the use of data codes to exclude bad or questionable data.
The "stacorr" oxygen, chlorophyll, and nitrate may have changed slightly. Please review the cast-specifics outlined
below for details on quality codes. The combined upcast and downcast db-csvs have been updated as well. All primary
and secondary plots were redone using the new csvs for quality-control.
The data problems listed in the original notes have not be corrected except bad data have been removed or data coded
as questionable or bad. Most issues were with the ISUS nitrate sensor but there were a few casts with other problems.

Specific cast notes 2017:
Cast 004: during the upcast, the cast had to be restarted so the two separate CTD upcast asc files were merged. The
downcast also had significant ISUS sensor drop-outs that were edited out of the downcast csv and data coded.

Cast 005: The upcast had ISUS sensor drop-outs from 458-437m, these data were edited out of the upcast csv and data coded.

Casts 009-012: ISUS battery was not powering the sensor so there are no data; data codes have been added.

Cast 065: data look like they may improve if loopedit was used. SIO-CalCOFI does not typically apply loopedit to
our CTD data since we use bottles to correct the CTD data. Bottle samples are collected when the CTD is stopped
at specific depths. Loopedit would filter these data out since the CTD is not moving (relatively speaking).
